, of which the following is a specification.

My invention relates to improvements in bobbin-holders orsupply-spindles for supporting bobbins delivering yarn to winding orother machines, the object of my improvement being to facilitate theplacing of the bobbin on its spindle and the removing or dofling of theempty tube.

My invention is fully set forth in the following speciiication,illustrated by the accompanying drawings, in which Figure 1 is a sideelevation of the bobbinholder, showing the bobbin in position fordelivering the yarn Fig. 2, a front elevation of the same 5 Fig. 3, aside elevation showing the position the spindle assumes when thebobbin-tube is removed.

My invention consists, in brief, of a tilting supply-spindle, which whentilted to remove an empty tube remains in this position until a fullbobbin is supplied, when It is automatically returned to its normalposition.

` In the drawings, a represents the supplyspindle adapted to it the boreof the bobbintube which may be of any of the wellknown forms asgenerally manufactured of wood. The spindle a is supported in a tiltingbracket b and held by the set-screw b2. The bracket is preferably formedwith two wings c and d, bored to receive the rod e, onv

which the bracket turns, a series of brackets being generally arrangedon the rod, with the latter supported in some convenient location on themachine. A collar f, adapted to enter between the wings c and d, islikewise bored to receive the rod c and is secured to the rod by anysuitable means, thus serving to locate and retain the bracket blongitudinally on the rod. I prefer to use the split collar f, as shown,fastened by a binder-screw g, which clamps the collar tightly on therod. The collar f is formed with a lug h, which engages the under sideof the bracket b to limit the turning of the bracket on the rod e, thusmaintaining the spindle normally in its upright position. The spindle a'is positioned beneath the tension device of the machine, which is hererepresented as of a usual form by dash-lines at i, and it is generallyrequired to have the top of the spindle closely adjacent the tensions.If the supply-bobbin were located at too great a distance from thetensions, in unwinding the yarn would fly out and balloon, and it is awell-known fact that excessive ballooning of the yarn causes addedresistance to delivery. To prevent this, it is advantageous to have thesupply-bobbin close to the tensions, but it will be seen that in orderthat the bobbin may pass the tension device in placing it on or takingit off the spindle the latter must be ada ted to tilt, as shown in Fig.3. Tilting supp y-spindles are well known in the art, and other meansbesides those just described might be employed for providing thisfeature of the present device.

y The novel feature o f the invention consists in means whereby thepresence of the bobbin upon its spindle insures the retention of thelatter in its normal operative position, while the removal of the bobbininsures that the spindle be retained in a different position, whichfacilitates said removal and. also the application of a new bobbin. I

The essential element of the device is a catch member j, preferablyformed of a sheetmetal piece with a central aperture, through which thespindle passes. The member is crimped or formed with a bend at k, whichportion rests on the top ofthe bracket b, presenting a rocker-bearing,the aperture in the member having play enough about the spindle to allowthe member to tilt or rock. The catch or lock is formed by bending downthe end of a projection of the member at Z, and this catch is adapted toengage a similar de'- tent fm, formed in a projection or lug on thecollar Two lugs jz and are formed on the member by bending down narrowstrips of the metal, and these lugs project downward between the wings cand d of the bracket b to prevent the memberj from turning, so that thecatch l is maintained in its appropriate relation to the detent m. Theweight of the bracket b and spindle c tends to maintain the spindlenormally upright with the bracket resting on the lug 7L', as shown inFig. 1, this being its position when IOO the tube or bobbin is in place;but when the spindle is tilted, as shown in Fig. 3, and the bobbin drawnoff the member y' is released and the force of gravity acting on theheavier end of the member j carries the catch l into engagement with thedetent m, so that the spindle is then held in its tilted position.

In practice the operation of my device is as follows: With the spindle ain the position shown in Fig. 3 the bobbin X is simply dropped onto thespindle and the head or bottom end of the tube x strikes the upliftedend n of the member y'. bobbin acting on the end n of the member y'tilts the latter and raises the catch l from the detent m, releasing thebracket and allowing it to drop into position against the lug hp rIhebobbin is now ready to deliver to the tension device i, as shown inFig. 1. After the yarn on the bobbin is exhausted the empty tube isdrawn ofl, and this necessitates the tilting of the spindle, so that thecatch Z engagesl the detent m. After the tube is removed the spindleremains in this convenient position, so that a new bobbin can be readilysupplied. The instant the fresh bobbin reaches its seat on the spindlethe catch lis released, and the spindle is automatically returned to itsvertical position.

It will be seen that with my device the placing of the bobbin and thedofling of the empty tube are greatly facilitated. The operator needonly use one hand, leaving the other free to thread the yarn in thetensions or otherwise manipulate it, while with other devices it hasalways been necessary to tilt the spindle with one hand and place thebobbin with the other, using both hands at the same time. It will beevident that a great saving of time and pains is accomplished by the useof my device, and its operation is most convenient.

Other means might be used for retaining the spindle in its tiltedposition and for releasing it when the bobbin is placed in positionwithout departing from the spirit of this invention. Therefore I do notlimit myself to the precise structure and arrangement here shown; but
